Overview:

Since virtualization is now in use across nearly all enterprises, and future plans to move some applications to Cloud Computing are also in the making, it is time to ask whether we need to update our IT security methodologies or continue to rely on the same tools we have relied on in the past.

Many would agree that these computing models require an entirely different approach. Often, it seems network security models lag behind the technology changes occurring in the systems and software environment they are intended to protect. For example, it took firewall vendors a long time to realize that applications are no longer easily protected by simply opening and blocking ports. As Enterprises began deploying VoIP and other complex protocols, they typically had to wait years before their firewall vendor allowed them to do so securely by analyzing SIP and other protocols.

This whitepaper suggests that with the recent changes in computing architecture from dedicated servers in the datacenter to virtualization and Cloud Computing, we need to rethink our IT security methodologies. And, while we focus in this paper on database security, many of the recommendations made here are applicable to securing most enterprise applications.
